چکیده

It has been hypothesized that, in species exhibiting natal philopatry, genetically related individuals would have home ranges closer to each other than those of unrelated individuals. Using radiotelemetry (2001–2003) and genetic data from 35 female Florida black bears (Ursus americanus floridanus), we tested the hypothesis that genetic relatedness among individuals influenced the spatial organization of home ranges. Genetic relatedness was negatively correlated with geographic distance between home ranges for each year and season (except autumn 2000), suggesting that genetically related individuals established home ranges closer to each other, whereas home ranges of unrelated females were geographically separated. Additionally, females that had overlapping core home ranges were more closely related than females whose home ranges did not overlap. These results are consistent with the hypothesis that genetic relatedness influences spatial organization of home ranges.

Factors Influencing Home-range Size of Female Florida Black Bears

The manner in which space is utilized by animals is influenced by several factors, including habitat quality and the distribution and abundance of resources. We used 4 years (2000–2003) of radiotelemetry data to investigate the space-use pattern of female Florida black bears (Ursus americanus floridanus) in the Ocala National Forest and an adjacent residential community of Lynne, north-central ...

Social network analysis of mating patterns in American black bears (Ursus americanus).

Nonrandom mating can structure populations and has important implications for population-level processes. Investigating how and why mating deviates from random is important for understanding evolutionary processes as well as informing conservation and management. Prior to the implementation of parentage analyses, understanding mating patterns in solitary, elusive species like bears was virtuall...

Genetic status of Asiatic black bear (Ursus thibetanus) reintroduced into South Korea based on mitochondrial DNA and microsatellite loci analysis.

The Asiatic black bear is one of the most endangered mammals in South Korea owing to population declines resulting from human exploitation and habitat fragmentation. To restore the black bear population in South Korea, 27 bear cubs from North Korea and Russian Far East (Primorsky Krai) were imported and released into Jirisan National Park, a reservoir of the largest wild population in South Kor...

Pathogenicity characteristics of Enterococcus faecium from diseased black bears

The death of several black bears at the black bear breeding base in Yunnan Pingbian Daweishan is a matter of concern. Multiple black bears exhibited decreased appetite or unusual waste, and some were soporific or suffered from vomiting and anhelation. In order to ascertain the cause of death, 16S rDNA gene sequencing and phylogenetic analysis was performed on bacteria isolated from tissue sampl...

Reproductive Ecology and Cub Survival of Florida Black Bears

We investigated reproductive ecology and cub survival of Florida black bears (Ursus americanus floridanus) in Ocala National Forest and the adjacent residential area of Lynne, Florida, USA, 1999–2003. We documented production of 81 cubs from 39 litters. Average litter size was 2.08 6 0.11 (SE) cubs. The mean age of first reproduction was 3.25 6 0.27 years. Excluding females that reproduced in c...
